Comparing Adaptation Strategies

butterflies and milkweed occupy the same habitat during the breeding season.
But when freezing temperatures approach, they show very different adaptations

When the two meet again in the spring, imagine how different their lives

the life cycles of monarchs and milkweed. Draw a picture of each during
each season: fall, winter, spring and summer.
- How are
milkweed and monarch survival strategies similar in the fall? How are
are physical or behavioral features that evolved in response to an
organism's environment, due to pressures for survival. How a species
looks (its anatomy and morphology), as well as how it behaves (moves,
obtains food, reproduces, responds to danger, etc.) are all adaptations
is a Behavioral Adaption
Monarch migration is a built-in survival strategy that
enables monarchs to 1) take advantage of North America's abundant
summer milkweed, and then 2) avoid freezing to death in the winter.

have basic needs. They can survive only in environments in which their
needs can be met.
- An organism's
behavior patterns are related to the nature of that organism's environment
- All organisms
must be able to obtain and use resources, grow, reproduce, and maintain
stable internal conditions in a constantly changing external environment.
- An organism's
behavior evolves through adaptation to its environment. How a species
moves, obtains food, reproduces, and responds to danger are based in
the species' evolutionary history.
